CLUE 6:
Ice Cube starred in the film “Boyz in the hood” that released late Summer of 1991, but was being filmed mid-late 1990 early 1991 and Ice Cube was busy on set filming the movie Jan 18 1991 too busy to be lounging around the streets with no plans. Ladies and Gentlemen..

The ONLY day where:
Yo MTV Raps was on air
It was a clear and smogless day
Beepers were commercially sold
Lakers beat the SuperSonics
and Ice Cube had no events to attend was…

UPDATE: In response to all this sleuthing, Vulture reached out to Ice Cube for confirmation of this fateful day but received only a cryptic, two-word reply: “Nice try.” No one knows what this means but it could have a profound impact on bloggers who are currently trying to prove that "Check Yo Self" was set on Jan. 21, 1992.
